The water-powered HydroCut self-propelled robotic cutter from Envirosight LLC uses high-pressure water to power a cutting head that clears roots from drain lines, mills offsets, removes groutflashing, reinstates laterals after lining and performs other tasks in 6- to 32-inch pipes.“High-pressurized water generates much higher torque and speed,” says Jake Wells, marketing manager. “As a result, it doesn’t leave rough edges. There’s no need for a second pass to perform brushing.” A 7.3 hp turbine motor spins the cutting head at 30,000 rpm. The cutter can completely mill away the liner from a service connection.The motor is water-cooled to prevent overheating,
